Vincario

Security checks for vulnerabilities and agentic risk

Overview

This Vincario skill is mostly purpose-aligned for read-only vehicle lookups, but its setup instructions tell users to run a remote installer script directly in a shell, which deserves review before installation.

Review and verify the oo CLI installation path before using this skill. Prefer official package-manager or manually verified installation instructions where available, and only connect the Vincario account and run actions when you understand the OOMOL connector permissions and possible credit charges.

  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

Finding

The skill instructs users to install software by piping a remotely fetched script directly into a shell, which creates a classic supply-chain and arbitrary code execution risk. If the remote host, script distribution path, or transport trust is compromised, users could execute attacker-controlled code on their machine with their own privileges.
